WILLIAM F, SWEET, OF JACKSON, PENNSYLVANIA.

Letters Patent No. 94,925, dated September 14', 1869.

MROVEMENT IN mmcams'r'rscmm TO WEIG-HING-SCALEE {the Schedule referredto in then Letters Patent and. put of the lame To all/whom it mayconcern:

Be a known that ,1, WILLIAM swear, of Jackson, in the county of Tioga,and 'State of Pennsylvania, have invented a new and useful Improvementin Scales; and I do hereby declare the following to be a full, clear,and exact description of thepsame, sutficient to enable others skilledin the artto which my invention appertains, .to makeand nsethe same,reference being bad to the accompanying. drawing, forming part of thisspecification, in which- Figure 1 is an elevation, and

Figure 2 is a detached view of the inner end of tlie balance-bar.

Similar letters indicate like parts. in both figures.

My invention relates to improvements in scales; and consists in theemployment of ahook situated in a removable frame, which may be attachedto any swayheam, the pages of said hook each containing a'calendar oftheprices at different rates perpound the article weighed will cost, theweight on the sway-bar pointing tothe price in thecalendar:

It further consists in the employment of a removable' balance-bar, whichmay be attached to any scale provided with a sway-bar, as hereinaftermore fully set fort-h.

In the accompanying drawings- E is the hollow standard of the scalcs,its lower end resting on the platform G. r

F is a rod, passing through the hollow standard and connecting thehopper-stand B with the ordinary lever employed at the foot of thestandard.

The rod F is enlarged at its upper extremity. 0,. and passes through ahole in the frame b. i

0 isa frame, pivoted at m to the arms S, on the standard E.

A is the sway-bar or beam, cast with the'fi'ame o.

By this arrangemeiit of parts it will be seen that any weight placed onthe hopper-stand, will operate the sway-bar.

cis .the sway-bar weight, having a pointer, x, on its extremity toindicate the price of the article weighed.

d is the rod, enlarged at-its lower end for the reception of theordinary slotted weights. D is a removable balance bar, the inner end ofwhich is constructed as seenin fig. 2, in' which a and f are projectingarms, which fit over the frame 0, and are attached securely to thesaidframe by the set-screws g g.

By this arrangement the balancc-banD can be removed from the scales, andcache applied to any scales having a sway-bar.

\V is a weight on the balance-beam D.

h is a book, placed in a removable'frame, N, attached to the sway-bar byset-screws, so that the 7 frame may be attached to any scales having aswaybar.

. The book is kept partially opened by a frame, 2, resting on its edgesand is attached by strings or otherwise to the frame N.

Each page oft-he book It is ruled vertically and horizontally, as seenin fig. 1.

The figures in theupper space, opposite the pointer a; of the weight 0,indicate the price of .the 'article weighed, at the priceperpound,'which is shownin the upper left-hand corner of the page.

The figures in. the second space opp site the pointer indicate in likemanner the price when a five pound weight is attached to the end of thesway-beam.

The figures in the third space in like manner indicate the price when aten pound weight is attached to the end of the sway-beam.

And spaces for figures may be added to the calendar forany weightattached to the outer end otthe sway-beam.

The object of placingweights on the end of, the sway-beam is to weighgreaten'weights than could be weighed without their use.

The pages resting on the bottom of the frame N give the prices forarticles weighed 'on the platform,-

while the other pagesindicate the prices for articles weighed on thesway-beam.

When the weight/W is at the outer end of the balance bar, and the weight0 at the inner end of the sway-bar, the scales are balanced.

Having thus described my invention,

What I claim asnewgand desire to secure by Letters Patent, is-

1. The application tothe sway-beam of ascale, of a book, substantiallyas-described, in such a ma'nner that the weight, when the scales arebalanced, shall in'dicate "the cost of the article weighed at aspecified price per .pound.

2. -The removable frame N, applied to the swaybeamof a scale forsupportingthe table or book h, substantially as herein described andshown.

3. The combination of the removable fiamsN and p, for supporting a book,it, and retaining it in an open position, substantially as described.

4. The removable balance-beanie D, constructed substantially asdescribed, and capable of application to anyscale of the kind specified,for balancing the scales with a vessel thereon, which vessel is to'contain the article purchased, before weighing the latter.

To theabove, I have signed my name, this 30th wday of March, 1869.

W. F. SWEET.
